How do I remove the Kinect, Unity, Human interface display in my game

I am working on a game in Unity that detects kinect using Primsense, Open NI drivers. In my game there is an AVATARNite script. It is a famous script and a lot of people have used it to make Kinect games on Unity.

I have a problem. I have seen youtube videos of many people posting their Kinect Unity games and they seem to have found a way to get rid of the human interface display (the purple and green figures that appear in the screenshot below). I want to remove those human interface displays from my game once the calibration is done properly (it just involves me checking some variable and having an if statement). What part of the code package contains the code for displaying those two figures there. I want to remove it coz it lags my game...

Can someone, who has worked with UNITY KINECT, help me?
